Title: Method of controlling suction of vacuum pad
Inventor: SONODA SHINJI
IPC: B25J15/06
Filed: 1987-08-21
Abstract: PURPOSE: To suck and detach without transmitting a reaction to a support part in suction or detaching a vacuum pad by constituting it in such a state as controlling the pressure of operating fluid, at least, into two stages. CONSTITUTION: A change-over valve 11' feeds high pressure P fluid to a terminal feeding hole 7 through a feeding hole 15 via a change-over valve 11. In this case, the suction pad 5' is drawn to a support rod 1. Secondly, the whole support part 3 is made to approach to the wall surface 6 to a prescribed distance so as to apply the vacuum. Then, when the feeding hole of the change-over valve 11 is shifted to 8, the vacuum pad 5' is pushed toward the wall surface 6 so as to start suction in such a position as bringing the vacuum pad 5' in contact with the wall surface. In this case, the pad 5' is pushed from the back so that as long as the reaction to the support part 3 is moving, it is not generated.  Thirdly, when the suction and the contraction of the vacuum pad 5' is completed, the change-over valve 11 is shifted, and when the pressure in the support rod guide part inside is set to the atmospheric pressure, the vacuum is turned off, the feeding hole of the change-over valve 11 is returned to 15, and the reaction to the support part 3 is set to zero so that the pad 5' is detached therefrom.

Abstract: PURPOSE:To attain a compact device by using a columnar or cylindrical information recording medium, rotating the information recording medium in a reading system and reading recorded information. CONSTITUTION:On the recording area 6d of the information recording medium 6, a recording layer 6b laminated by applying or depositing on a columnar or cylindrical base material 6a and a protecting layer 6c protected from a flaw or a dust are laminated. Since a reading is executed by rotating the information recording medium 6 and moving a reading part in parallel, the movement of the reading part is narrowed more than the reading by a crisscrossed movement to make the entire device small-sized like an optical card. A light from a light source (LED) 18 is equalized by collimator lenses 19, 20 and a diffusion plate 21 and is projected on the information recording medium 6 through a half mirror 27 and an objective lens 23. A reflected light from the recording layer 6b forms an image on a photosensor 22 by the objective lens 23 and converted to an electric signal by the photosensor 22.

Abstract: PURPOSE:To form insulating layers and wiring layers at every one layer by shaping via holes having center points at points, where directions are changed centering around a lattice intersection, in succession every time layers are altered while being separated only by specified distances from the lattice intersection or a specified point. CONSTITUTION:The conductor lands of squares having length (a) of one side are formed in the same size from a lower section to an upper section, and a wiring 14 and a land 15 are shaped in the same plane to a form that the wiring 14 and the land 15 are continued in a first layer. A hole having a diameter (b) is bored distributed unevenly only by [via-hole diameter b)X1/2+DELTA] from X and Y axes in a first quadrant centering around a lattice intersection O1. Via holes are shaped to a winding stair shape at the same center distance in the clock-wise direction toward an upper layer as a fourth quadrant in the via hole 17 between II-III layers, a third quadrant in the via hole 18 between III-IV layers and a second quadrant in the via hole 19 between IV-V layers, and reach to an uppermost layer. Consequently, the inter-layer connecting via hole of one layer and the via hole of the layer nearest to the layer are not superposed. Accordingly, the effect of stepped sections is eliminated, thus forming insulating layers and wiring layers at every one layer.

IPC: H01F7/02
Filed: 1993-08-20
Abstract: PURPOSE:To operate a compressor with no lubrication by applying a permanent magnet, which connects both a swash plate and a piston contactlessly by magnetic fields opposite to each other, as a mechanism, which connects the swash plate for converting rotary motion of a drive shaft into swivel motion and the piston, so as to eliminate wearing in both the swash plate and the piston. CONSTITUTION:When a drive shaft 8 is driven, since each double head piston 15 makes a reciprocating motion in each cylinder bore 4 in accordance with a tilt angle of a swash plate 14, a compression chamber of causing changing the volume is formed in each cylinder bore 4. As a result, in the compression chamber on the way of spreading the volume, low pressure gas is sucked from the outside via a swash plate chamber, suction chambers 6a, 7a, suction port of a valve plate 5, etc. On the other hand, from the compression chamber on the way of contracting the volume, high pressure gas is delivered to the outside via a delivery port of the valve plate 5 and each delivery chamber 6b, 7b. Here by utilizing magnetic fields opposite to each other by a plurality of permanent magnets 14a, 14b; 15a, 15b, the swash plate 14 and each double head piston 15 are contactlessly connected. In this way, wearing of the swash plate 14 and each double head piston 15 is eliminated.

Abstract: PURPOSE:To enable precise positioning control by furnishing cylinder having a non- circular cross section with an operating shaft which rotatably penetrates the cylinder and two pistons which, with backlash, are meshed with the male screw of the operating shaft, have fitting backlash between themselves and the cylinder, and adjoin each other with a clearance. CONSTITUTION:When pistons 14 and 15 are located on the left end side of a cylinder 10, and operating fluid is sent into a chamber 17, the operating fluid pushes the piston 15, simultaneously flows into an inside circumferential side clearance part 13 through fitting backlash between the piston 15 and the cylinder, and pushes the piston 14. The piston 14 rotates in a direction so as to leave the piston 15 and is released from locking. The pistons 14 and 15 travel in parallel to the right end, and an operating shaft 11 rotate. When both pistons reach the right end of a male screw 12, the piston 14 is prevented from further travel and the piston 15 approaches the piston 14 by operating fluid. Meantime, the operating shaft 11 also rotates, and the non-circular piston 14 rotates by its fitting backlash, makes contact under pressure with two points of the inner wall of the cylinder 10, and stops. The piston 15 also makes contact under pressure with the inner wall of the cylinder 10 and stops. Movement to the left end is performed similarly, promising precise positioning.

Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To secure a good communication state by identifying the sort of a receiving side connection line, setting up a transmission level in accordance with the identified result and setting up an incoming level to a suitable level. SOLUTION: A transmitting side calls an opposite party in the case of a PST call, and after closing a line, detects a previously determined tone signal. When the tone signal can not be detected, a normal transmission flow is executed in the state as it is, and when the tone signal is detected, the sort of a receiving side line is specified from the frequency of the signal detected by a tone receiving part. After receiving an incoming call by an ISDN control part, the receiving side B compares a CSI registered in a RAM with a similar CSI for communication, and when there is a difference, judges a change in the line connection state of the receiving side equipment itself and sends a tone signal of prescribed frequency indicating that the connection line is ISDN. Then the receiving side executes a normal receiving flow.
